Loved the sleeping bag. Kept me warm and comfortable throughout 2 weeks of sleeping outdoors. Only addition I would make is a bivy cover or other waterproofing device.
Y’all may sell those on your website (I haven’t checked). But I think it should come as part of the sleeping bag.
Great product overall

I purchased this bag with the express purpose of keeping me warm on my summit of Kilimanjaro (Africa's highest point at 19,341 feet.) Our highest camp was at 15,200 feet, two of our camps were around 13,200 feet, with two others at 12,200 feet.
I can say that once I got in and warmed up, I absolutely stayed warm. I run cold, and I'm uncomfortable when I'm cold--so needless to say, I had to have a bag that would sustain my warmth at the high altitudes. The H&B 0F Katahdin synthetic did not disappoint! The bag is very comfy! It is roomy enough to roll over in the night, or reorganized yourself as needed. The zipper did not snag but a few times. It is lightweight and it packs down well for a synthetic. I would highly recommend it. We reached the summit and it was glorious. Thanks for keeping me warm!

Best sleeping bag I’ve ever had. Took it scouting for this years elk season. In northern Colorado, weather got down to 19°F at 11000ft and it kept me pretty well insulated, didn’t feel that bad at all. Very compactable and light weight if you were planning for a backpacking trip.

I have only laid in this in my living room. It seems well built and most likely to keep me warm at 9000 feet in the mountains in September. I can give a better review I use it there in September 2021.
Karmen M.
Love the product, I mever received the sticker to promote your business on the back of my camper though.

This is a very comfy and warm sleeping bag! Took it out to the desert and temperature got down to 15 degrees and I stayed warm! What I really like about it is the material inside allows you to roll to your other side (I am a side sleeper) without rotating the entire bag! While hiking, the bag compresses small to make room for other items in your backpack. Would definitely recommend to anyone!

I am excited to use the New bag in the BWCA this some.
I won't be cold again!

Excellent 0 degree bag! I've used this multiple for backpacking and camping trips. Good quality, very lightweight material. Kept me warm in low 30s overnight at 1,800 feet of elevation. Overall very satisfied with this product!
Ignacio C.
Excellent bag!!

I will be using my bag this fall at 10,000 feet in the mountains of Colorado. So far I am very impressed with the quality and Hyke And Byke. I am very confident I will have a great experience. One of the guys going with me in November was so impressed with my bag, he bought one also. Thanks H an B!

Using it for the first time this weekend. Works great with my sleep system setup on my Living Room floor lol.

Bought this bag for a grandson to use when Boy Scouting in the winter months. He has used twice on campouts. Temps ran from 16 degrees fahrenheit to the low 20's. He has stayed warm. Requires 2 persons to put into stuff sack and be quick or it pushes it self out again. He is happy with the weight and size when backpacking. I am satisfied with quality and warmth.
michael m.
just tried it in my back yard and slept like a baby, of course without the crib.
Deborah C.
Gave this as a gift to my son. He was expecting it to pack down to a much smaller size, based on the pictures he saw of it.
Sola m.
It's a great product
Chris M.
Bag is super comfortable and definitely warm in cold temperatures. Only reason for 4 stars instead of 5 is that getting the bag compressed back down to its original size took several tries. Could be user error, so I’m willing to update my rating after a few more trips. Definitely a great value for the price!
Steve W.
Very good quality bag. Exactly as advertised!
George S.
I havent used it yet
Heather A K.
Great bag! Spent several single digits nights car camping while traveling across country. Very comfortable...
Steven L.
I've so far had my 0 degree synthetic in 15 degree nights twice. I wake up cause I'm sweating and have to unzip it some to cool off. Absolutely amazing at less than half the cost. This will be my forever brand of bags for my entire family. 3.5 pounds and fits in the bottom of my pack.
dana b.
Very warm, very affordable. This is a great alternative to the REI 0 degree down sleeping bag.
Susan M.
I purchased it as a gift for my son - he loves it!
Gregory R.
Haven’t used it yet but it’s very compact for a 0degrees bag.will let you know when I get back from from kodiak all this fall
Chris H.
Awesome. Light weight and keeps me comfortable up in northern Arizona.
Melanie C.
one of the best bags I've ever had. Loved th fast shipping and the quality. I may have to get a hammock. Thanks!!
Joel H.
Bought this as a Christmas present for a family member and he loves it!
Shay M.
I love it the quality is great. It has a hidden tech pocket in the collar, easy to miss. Warm foot box. Love the feel of the material. I also bought a down bag and while i like it a lot too. This one has me preferring it as i don't worry about the down shifting around and i don't worry about moisture.
Kevin Y.
It's warm, comfortable, and light weight.

Love it
I see quite a few negative reviews on here however that has not at all been my experience. I bought one of these bags a few months back and have taken it out on two weekend backpacking trips. The first trip temps dropped to between 15°-20° at night and I was more than surviving, I was hot. I ended up stripping down to my compression shorts and giving my girlfriend all of my extra layers to insulate with and I still woke up with some sweat. I tend to be pretty hardy in the cold and put off a lot of body heat so maybe this won't be everyone's experience. I also haven't had the bag long enough to know if this performance will substantially decrease over time. All I can speak from is my experience and it's been great! The bag is light and easy to strap onto a backpack although the straps on my 85 liter are almost too short to go all the way around. It looks a little intimidating to repack but compresses easily even with cold stiff fingers. The negative side of this is that I suspect this bag won't be super durable and will probably tear more easily. I think this is a great budget cold gear bag and I would definitely buy again.

Fantastic Cold Weather Bag
My fiancé and I are avid campers/backpackers and spent weeks researching for a new cold weather sleeping bag. We decided to purchase the Katahdin 0' as we did not want to spend $$$ on real down filling - and did not want to worry about the real down getting wet. We were extremely happy with this sleeping bag! I'm a bit claustrophobic and was worried I'd feel too constricted in a mummy style bag but there is plenty of wiggle room! We both love that you can use the draw string to ensure the top part of the sleeping bag stays secure around your head. Our first trip out with the Katahdin bag, the temperature dipped to 30 and we were super warm - I even had to take a layer of clothing off I was so warm! I expect that this bag will perform just as well in colder temperatures. Make sure that when you are not using the bag to store it either on a hanger or laid flat so that the filling stays nice and fluffy.
For the negative reviews of warm in extreme weather - remember that the temp rating on a sleeping bag is the SURVIVAL rating, NOT the comfort rating. Meaning, you'll survive if the weather is 0 degrees, but you probably won't be comfortable. Always add about 20 degrees to the temp rating to figure out the comfort temp.
Adam
Literally threw this bag in the trash
It felt good to throw this bag away and know that I will not be spending any more sleepless nights freezing my butt off and praying for morning. I would not recommend this product to my worst enemies, absolutely terrible. If you are considering buying anything from these guys, make sure you look at the date stamps on all of their reviews, kinda suspicious that most of the five star reviews came in on the same date.

Very Poor Performance
I bought this bag expecting to spend nights at high elevations in the Rockies year round. I've had 0° synthetic fill bags in the past and have been very comfortable. This bag should not have a 0° rating. Even at nights around 45°-50° this bag is not warm. At temps in the mid teens it is VERY UNCOMFORTABLE. A big part of the problem is that the fill migrates out of the baffles every single time you use it leaving you with 2 thin layers of nylon for warmth. Each night before bed, expect 20-30 minutes of attempting to redistribute the fill only for it to be lumped up in one spot by morning. I can't see how this bag has such a high customer ratings unless you aren't using it or you are generating false reviews for these guys. Also, they're customer service and warranty is a joke. I would highly recommend spending a little more money and get yourself a well made product from a trusted brand that will honor their warranty.

Katahdin sleeping bag was not as expected :(
Katahdin sleeping bag was not what I expected, I got this bag and as soon as I did I opened it up and let the bag breath for a couple hours to give the fluff time to...well puff up and once I came back I began to work the fluff into various bald spots around the bag(which is to expected with all bags like this) after that I proceeded to lay in it and get a feel for it which I thought felt pretty comfy and warm but just to mess around and experiment I put my $25 on full blast (the fan kinda sucks btw) I began to feel the air hit the bag and to my shock and horror I felt the cold start to hit my arms but I wrote it off as a fluke so I waited to take it out camping and to make a long story short this product fell very short of my expectations, consider getting something like the goose down bag if you really want a good bag that will be good at keeping the cold out and warmth in, if I had another chance to buy a bag I would go with the goose down one because now I have to save up again to throw down on one that will keep the cold out :(

Warm at 11,500ft in 11° weather
Bought for backcountry elk hunting in September. It gets really cold at night at treeline & this bag did the trick! Thermal base layer when below 20°, tshirt & underwear when above 30°. Super light & packs down very well, same size compressed as my 20° Exponent bag. I really want to try one of the down bags - can you make sure to pull my name for the monthly drawing for that? LoL

I was surprised!
When I received my bag I thought no way is this going to be warm in 20deg weather. I waited for a cold night, 30deg. Hopped in the bag with an insulated pad with just my boxers. During the night I unzipped my bag because I was a bit too warm. What a great bag! It’s refreshing to find a company that sells a great product at a great price. I’ve been backpacking and solo backcountry hunting for over 30yrs. This will be with me on all my cold weather outdoor activities. Hyke in Byke Thanks for a well priced product that exceeded my expectations

Amazing Bag
I bought the 0 degree Fill bag a month ago and when I received it in the mail, I thought that there was no way this will keep me warm in 18 degree temps....It is so light I didn't think there was enough insulation to work. But I just used it in the mountains of western Maryland the weekend of Dec 20 -21st, and I was amazed. I wore military polypro base layers and a fleece watch cap. Underneath the bag I used a Coleman self inflating pad to keep me off the cold hard ground. I was comfortable on night and slept well. I am 6ft 1 and I bought the Tall bag and had plenty of room. I probably could've gotten away with the regular size bag. It's an excellent bag. Well made and compresses well.

0 degree hydrophobic F625 synthetic bag.
I am a 70 year old retired male.I just spent my first night sleeping in my 0 degree F625 synthetic bag. Temp was 18.2 degrees F when I woke in my tent in the morning. I wore long johns and a down vest and I was comfortable all night.This bag feels warmer than my older bag ; it is the 0 degree snowmass F 650. I am 6ft 3in 200 lbs so I ordered the long sized bag and it fits fine. I will try this bag on a colder night and see how it works.Nice bag so far!!

Sizing seems off
I'm 5'10 and have wide shoulders. Ordered the regular and is a bit short in length and tight around the shoulders. Midsection fits fine but definitely difficult to zip around the shoulders. Feels cramped. Will have to exchange sizes.

4 stars only because too warm to actually use it & can't give proper warmth review
This is a provisional review. I purchased this bag in May and it is just too warm out to give it a proper test.
That said, I'm quite happy with my purchase and impressed with this bag. I'm over 6' tall so I ordered the extra long. As one of my images shows, I weighed the bag, in it's compression sack, and it was actually half a pound less than listed. Concerned that I was sent the worng size (the actual weight matches the weight listed for the Regular length,) I measured the bag. It's the Tall, so looks like Hyke & Byke is conservative with their weights.
While I had the tape measure out, I measured the loft - a solid 5.5". Not bad.
I was impressed by the zipper pull and figured it worth of a picture.
I crawled in the bag and was also impressed by the feel. It's fairly roomy, and the insulation felt quite down-like. It's been years since I've used a synthetic bag and insulation has come a long way.
I look forward to trying this bag this autumn.

Light and warm but weak material.
The Good:
As other reviews mention, almost uncomfortably warm bag, probably ideal for fall conditions (see below about sweat). Finding a compressible bag at this price with this weather rating is unheard of. About the same size in the pack as my friends' down bags.
The Bad:
Was excited to see a synthetic down hiking sack at a decent price with a great weather rating. Unfortunately the bottom caught in the tent zip the first night and even gently unzipping the snag the bag tore. This is remarkable given how many times during the wind storm this bag was used in other things including the tent itself were caught in the zipper and came out unscathed. The other issue is that the interior of the bag is the same material as the outside. What you end up with is being stuck and sweating to the inside of the bag. I feel there must be a breathable lightweight synthetic for the interior that would solve this.

Extremely impressed!
My new bag just arrived and I couldn't be more impressed with the qualify of this bag for the price and weight. The zipper is very smooth, even using just one hand, and the amount of loft in the bag is impressive. The draft collar sits just a touch below the neck line, which I found to be less claustrophobic than when pushing against my neck as some designs do. There was also an generous amount of loft in the foot box. I haven't had the bag in the field yet, but I've owned my share of bags and have no doubt this one is exactly what I've wanted for weekend winter backpacking trips. It even comes with a nice compression sack! Thank you for a great product at an amazing price!

Jim Williams
Very happy!
I’m going to be honest, I didn’t expect this bag to work out. Typically, inexpensive bags are cheaply made, and don’t live up to their description. I rolled the dice and decide to give it a shot. Took it out overnight in temps reaching the low 20’s/high teens. I was very comfortable all night. At one point my dog got too cold so I opened the bag quilt style and covered him too. Even open, we both stayed toasty. The stitching seems to be of good quality and the zipper and draft collars are better than some $400 bags I’ve owned. I used it with a sleeping pad with an R value of 3 and a standard 3 season base layer. Would recommend.

Amazing bag!!!
This bag is so light and so warm- went camping with it on the weekend of the first frost in the Rocky Mountains and stayed warm all night. The biggest deal to me is that the bag is SO easy to pack away- no trying 4 times to have it not fit in its bag. Well made, super warm, easy camping/backpacking bag. I’m a Hyke and Byke customer for life now!

Very good value!!
Was replacing an older 0 degree bag that was 3-4x bigger than this one so very happy with the weight and space saving. Got to use on a camping trip the week I got it and was pleased, very soft, seems to be constructed well. Awesome value so far!

Quality Bag!
Recently used the Hyke and Byke bag on a week-long backpack trip in the Southern Utah canyons . Temperatures ranged from 30-42 degrees. It was very warm, almost too warm. The bag performed well, was easy to pack, and maintained its form. I think it performed as well as the down bags this company makes. Another winner!

Perfect bag - Amazing price
This is an incredibly warm bag. It packs small, is very light and well made. I have several bags from Hyke & Byke and I love them all. The shoulder width on this bag is narrower than some of their other bags so that is something to consider when comparing their bags. I am 6ft and 290lbs so I need more space. I fit in this Long bag just fine. At this price point there is no competition. You won’t be disappointed. Nobody gifts me anything. I buy from Hyke & Byke because they make good products.
